About Sheng Si Island
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces NE (37°), so it takes swell from the NE. The wind blows offshore from the SW (217°). It is exposed to the open swell. It suits beginners and up. It works in 1–6 ft of swell. The sea floor shelves very gently: 10 m deep about 3.4 km out (1 in 345). On a typical 5 ft, 11 s swell the waves here would spill softly. The sea is about 10°C in February, its coldest month (4/3 or 5/4, boots and gloves), and 27°C in August, its warmest (no wetsuit). The town to stay in is Caiyuan.
Water about 20°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
The score is the conditions only: the journey, the price and the partners never change it (how we score, how we earn).
